Unclear Nothing shows what this switch controls or where Claude Code uses it.

What

Claude Code has a new check that reads a remote switch called tengu_nifty_harbor. A remote switch is a setting Claude Code reads from Anthropic's servers. If the server sends nothing for it, the check treats it as on. Nothing yet shows what the switch controls.

Why

The switch is present in this build, but its effect on Claude Code is not known.
